matically transferring water from a boiler.

'to a filter in the coffee pot, and of automatically removing said boiler from over the lamp, and placing said coifee pot over said lamp; and to suchends my invention consists in the automatic coffee potv hereinafter specified.

In the accompanying drawings 1 have illustrated one embodiment of my 1nvention, but such embodiment is to be regarded as typical only of many possible embodiments.

Figure 1 is a side elevation of one embodiment of'my invention; Fig. is a vertical sectional view through the boiler and lamp support; Fig. '3 is an end elevation showing the coifee pot in section; Fig. 4' is a top plan view the coffee pot and boiler being removed; and Figs. 5 and 6 are respectively a side elevation and a front elevation of the supportin post and sleeve andthe parts immediate y carried thereby.

In such embodiment I khave provideda base 1, having thereon a lamp-support 2, in which rests a lamp 3, such, or instance, as an alcohol lamp. Thel support 2 carries a bracket 4, uponS which is hingeda cover 5, that is adapted to fit over the lamp. The said cover is provided with an opening 6, through which the flame may rise. A valve is provided for exposing'or closing the said opening, and such valve, as illustrated,` consists of a disk 7 of suitable size for covering the said o ening, said disk being mounted on the en also preferably provide stops 10 and 11, formed by the bent-up ends of a stri that is secured in the said cover arms, w ich sto s limit the extreme movements of the sai lever. A post 13 is mounted u on the said base and a sleeve 14 upon the said post. rlhe lower edge l5 of said sleeve is formed into a spiral or screw,fwh,ieh is ada ted to rest upon a stop 16 fastened upon t e said of a lever 8, that is, fulcrumed' .as upon a screw 9 on`the said cover arm. I

' post, and preferably having an upper surface inclined to correspond with the incline of the said screw, in such a manner that as the sleeve descends upon the post, as later described, its inclined surface act-ing upon the said stop, tends toturn the sleeve and the parts carried thereon. The said sleeve is provided Kwith a bracket 17, or other form of support, which, in the 'present instance, carries screws '18, upon which the coffee-pot proper is mounted, as hereinafter described. The said bracket also has ears, between which is fulcrumed a lever l19. The said lever has a vertical arm 20, upon which is mounted a hook 21, that is adapted to eng'age a pin 22, mounted in or upon the vertical post. The hook and pin are correspondingly beveled, so that as the hook approaches the pin, in the rotation of the sleeve upon the post, its beveled face shall ride over the beveled face'of the pin, and its vertical face engage the verticalface on the far side of the pin. Upon the said screws is mounted a combined coffee-pot and boiler, consisting of a coffee-pot 23 and a boiler 24, connected as by bars 25, the said bars having notches 26 that are adapted to lit over the said screws, so as to support and fulerum the said combined structure on said screws. The coffee-pot and boiler are also connected preferably at other points by braces, so that they are rigidly fastened together. may be closed substantially steam-tight by a cover, the latter being preferably screwed on to the can. A pipe.27 extends into the said can and nearly to the bottom thereof, and enters the can 28 of the coffee-pot near the top thereof. A small vent is preferably provided in the boiler cover, so as to permit the escape of air until steam is formed.

Within the coifee-pot are provided any devices which will serve to make coffee, but preferably some form of lter that will hold the coffee well above the bottom of the coffee-pot, so thatl water may be filtered through the coffee and pass entirely below the same. The said filter in the present instance consists of a cup 29, having a flange that is ada ted to rest upon lugs 30, formed A sieve 31 closes the lower end of the cup, and there is preferably also a plate 32, which has perforations small enough to prevent most of the coifee grounds from passing therethrough.

In the lower end of the coifee-pot is a The boiler consists of a can that spigot 33, from which the'made coffee can be drawn.

The rear end of the leveris adapted to support the boiler,"and the front end of the the lever, which engages the bottom of the the upper surface of the water,wil1 force waboiler,` and inside of a flange lformed thereon.

In the operation of my coffee-pot, the

combined coffee-pot and boiler are turned.

until the boiler is over the lamp, in which position the hook will have engaged its stud, and the sleeve be thus locked in its highest position. The water in the boiler also will keep the rear end of the lever tipped down, and thus keep the hook in engagement with the stud. The lamp being lighted and regulated, will heat the boiler and gradually form steam therein. The steam pressing on ter through the pipe and over into the cup within the coffee-pot. There the water Will filter through the coii'ee Within the said cup,

and pass to the bottom of the coffee-pot ready touse as coffee. When alllthe water in the boiler has been forced over into the coffee-pot by the action of the steam, the center of gravity of the combined coEee-pot and vboiler will have changedl from the rear side of the lever to the forward side thereof,

andthe coffeeot'will tip down, raising the boiler and raising the rear end of the lever, and disengagin the hook from its pin.

The weight of t e parts will ythen cause vthe screw surface on the sleeve to slide down on the beveled lug upon which it rests, thus turning the sleeve until the boiler has been removed from over the lamp, and the coffeepot has been swung over the lamp. In this position the made coffee is kept heated by the lamp.

It will be observed that the action of my coffee-pot is automatic, and that it is not necessary to Watch it to see when the coffee is completed, and to prevent burning the boiler by the continued "application'of heat after it is empty, nor to take any trouble to see that the coffee is kept hot.

Itis obvious that various changes can be made in the above illustrated-construction which will embody the spirit of my invention, and I desire not Ato be limited beyond the'intendment of my claims, or the necessary requirements of the prior art.

`1. A coffee-pot, comprising a coffee-making device, consisting of a coffee-pot and a boiler, a connection therebetween for transferring water, a'lamp, and means for automatically removing said boiler from said lamp, andj'applying said lamp tosaid coffeecoffee-pot above the bottom thereof, a lamp, and means for holding said boiler over said lamp until the Water has been transferred to the coffee-pot, and for then removing said boiler from said lamp and bringing said.
